Novak Djokovic speaks. “I’m very pleased. He started off with a break. He made a couple of great shots but I managed to break and get back into the set. He’s got weapons, a big first serve and a big forehand, but I managed to get serves back and make him play another shot. It was really difficult conditions to play in. The last couple of games, I couldn’t really see the ball very well. Hopefully I can carry today’s win into the next match.”

Novak Djokovic will play Kei Nishikori on Wednesday. He’s looking very impressive at the moment. He hit 29 winners, converted seven of his 14 break points, got 71% of his first serves and was always in control after dousing Karen Khachanov’s early fire. Djokovic still has much to prove given that there have been plenty of false dawns with him in the past two years, but he looks fit and is a definite contender for the title.

Novak Djokovic beats Karen Khachanov 6-4, 6-2, 6-4!

When Novak Djokovic is returning well, you know he’s feeling good. Karen Khachanov saves two match points, but Djokovic wants this done now. The Russian nets a backhand on the third and this is over. Djokovic gives the crowd on Court 1 some love. He’s all smiles tonight.

Play has been suspended on Court 2 because of bad light. Juan Martin del Potro leads Gilles Simon 7-6, (1), 7-6 (5), 5-7 and will hope to get the job tomorrow. It isn’t ideal for either player. It means that the winner won’t be able to rest before a quarter-final against Rafael Nadal on Wednesday.

The fading light on Court 2 has worked against Juan Martin del Potro. Facing set point at 5-6 in the third set, he batters a serve at Gilles Simon, who returns with interest. It’s close enough Del Potro for him to continue the rally, but he leaves it, thinking it was out. Nope. Bang on the line. Del Potro challenges, but the third set belongs to Simon, who trails 7-6 (1), 7-6 (5), 5-7. I don’t think Del Potro could see it properly. Both
